I have been trying to fix my friend's Sony Desktop VAIO PCV-RX755 P4 2GHz/512/80/DVDRW, on
which a technician, from a local PC Shop, gave up.
PC would not boot, with a message displayed "NTLDR not found,
Ctr+Alt+Del to restart".
I replaced the original HDD with IBM's and successfully loaded Windows
XP Pro. However, none of the VIDEO, AUDIO, or Ethernet works.
In device manager:
- there is no Display Adaptor Icon, or monitor icon even Present,
- Audio driver - present and shows "This device is working properly"
- there are two yellow question marks listed as unknown devices.
All Audio , Video and Ethernet are on board integrated.
I have updated BIOS, installed Sony System Shared Folder, Video driver,
Audio Driver, Ethernet Driver - all in accordance with Sony's website
Technician at Sony was not very helpful and only recommended to take
PC to a Service Center.
COULD SOMEONE TELL ME WHAT'S GOING ON WHITH THIS MACHINE, AND ADVISE ON HOW
TO FIX THOSE DRIVERS, besides replacing SONY's MB and HDD, followed by A
Quick restore. Is there a "special way" to do it for SONY's PCs?
Go to Sony's website and look for drivers for that specific model of laptop. If that doesn't work, at least find out what sort of hardware is in it (you should be able to get a detailed spec sheet at the very least from Sony) and download drivers that way.
The other solution is, of course, to use the Sony restore CD. That should install any drivers that are needed.
